CS1525：无效的表达式术语“)”

Question

I'm working with Telerik Grid and I want to have a column using the Template to acces to other accion. The code I have in the Grid is:

columnas.Template(o => 
{
    %>
       <%=Html.ActionLink("Texto","Prueba","Peticion", new { id= o.PeticionID }) %>
    <%
}).Title("Prueba");  

When I run the application I get the error:

CS1525: Invalid expression term ')'

And it show the { character after o =>

Any idea about what I'm missing?

Answer 1

From the point of view of the C# code (not including server tags), the lambda expression in columnas.Template is empty... which will result in an error.

effectively what you've written is this:

columnas.Template(o => { }).Title("Prueba");

Answer 2

I had the same problem and managed to track down the answer.

From http://www.telerik.com/community/forums/aspnet-mvc/grid/invalid-expression-term-in-template-statement.aspx

Basically, if you are using column Templates then your grid code should be:

<% Html.Telerik.Grid()
-
-
.Render();%>

instead of:

<%= Html.Telerik.Grid()
-
-
%>

It's hidden fairly well in here:

Answer 3

There is a really good chance you have an extra ) somewhere at the end of the Grid method.
